# Inversion test
|
||
|
|
|
||
|
|
This is a test setup for inversion calculation with teleseismic events.
|
||
|
|
|
||
|
|
1. Run all cells of `make_test_model.ipynb` for creating
|
||
|
|
- source, receiver file (src_rec_test.dat)
|
||
|
|
- true model (test_model_true.h5)
|
||
|
|
- initial model (test_model_init.h5)
|
||
|
|
|
||
|
|
2. then run TOMOATT forward with `input_params_pre.yml` for calculating the true arrival times at the stations
|
||
|
|
At first, TOMOATT calculates 2d traveltime field for each teleseismic event.
|
||
|
|
TOMOATT will find the event source is teleseismic if the event origin is outside of the simulation domain.
|
||
|
|
Calculated 2d traveltime field is saved in OUTPUT_FILES directory with 2d_travel_time_field_{src_id}.h5
|
||
|
|
2D solver run will be skipped if this file is found by TOMOATT.
|
||
|
|
Result travel time at the stations is saved in the file `src_rec_test_out.dat`
|
||
|
|
Following command will run the forward simulation with the true model
|
||
|
|
``` bash
|
||
|
|
mpirun -n 8 ../../build/TOMOATT -i input_params_pre.yml
|
||
|
|
```
|
||
|
|
Volumetric output data is saved in the file `OUTPUT_FILES/out_data_sim_0.h5`.
|
||
|
|
This file may be visualized by paraview with opening the index file `OUTPUT_FILES/out_data_sim_0.xmf`.
|
||
|
|
|
||
|
|
3. run TOMOATT in inversion mode with `input_params.yml`, by the command
|
||
|
|
``` bash
|
||
|
|
mpirun -n 8 ../../build/TOMOATT -i input_params.yml
|
||
|
|
```
|
||
|
|
The volumetric output data is saved in the file `OUTPUT_FILES/out_data_sim_0.h5`.
|
||
|
|
|
||
|
|
|
||
|
|
4. For retrieving the output data from *.h5, please use the python script `utils/tomoatt_data_retrieval.py`
